MAQEa'AGING DEVICE.

Application filed February This invention relates to a motor-driven machine for massaging, rubbing or manipulatingthe scalp of the human head, of that type shown and disclosed in application Serial No. 136,421, filed September 20, 1926.

Although the type of device disclosed in the above-mentioned application is adaptable for use suspended from a suitable support as well as entirely held and supported by the operator, the object of this invention is to, provide a device l'iaving a vertically positioned motor and driving mechanism, which particularly adapted to be used suspended from a suitable support, although quite capable of being manipulated. when entirely held and supported by the operator.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Figure 1 is a side elevation. of the machine with a portion thereof broken away and showing parts thereof in dotted lines. Fig. 2 is a plan View looking down on the machine. Fig. 8 is an end elcvation with a portion thereof shown in vertical cross section.

In the drawings there is shown a massage machine or mechanism comprising an electric motor 10 which is vertically mounted in a housing extending vertically with respect to the machine, the lower portion of which terminates in and is formed integral with the main housing 11 of the machine. TC):- tending vertically downwardly from the motor there is a driving shaft 12 having a worm 13 thereon which is adapted to mesh with the worm gearsl l oppositely disposed on each side thereof. Through the medium of the motor and worm, the worm gears 14 will be caused to rotate in opposite directions a relatively low or reduced speed.

Each of the l-el is keyed to assleeve 15 into which a driving pin 16 is secured and locked, said pin having a reduced bearing portion 17 rotatably mounted in a bearing 18 formed in one side of the housing 11', while it is supported on the opposite side of the gear in the bearing 19. Keyed to the driving pin 16 there is a driving cam 26 which is eccentrically positioned thereon, said cam being circular in formation and having a driving collar 21 positioned about the pe riphery thereof. The collar 21 is connected with a connecting arm .22 which is pivotally Serial No. 168,414.

connected with a stud 23 formed on the supporting frame 24.

The supporting frame is curved in the form of a yoke having anopen end which adapted to telescope with a projecting portion of the frame 11 indicated by the numeral 25. By means of this arrangement the rotation of the worm gear 14: will cause the cam to rotate within the collar 21, thereby imparting a reciprocatory movement to the supporting frame 2%, saio supporting frame being provided with barrels 26 which are slidably mounted on the guide pins 27 extending from the projection of the housing. it will be noted that the supporting frame by reason of its openend telescoping with the projection 25 of the housing, will completely enclose that portion of the driving mechanism including the cam, collar and connecting arm, so as to protect the same as well as the [hair of the scalp upon which it may be user.

The supporting frame 24 is formed with laterally and downwardly extending arms 28 and 29, the arm 29 being connected and supported by a bowed connection 30 passing under the housing 11. The worm gears 14: are further enclosed in conjunction with the housing 11 by the semi-circular housing 31. which is shown. removed in Fig. 3, said lionsing 31 being removably secured thereto so as to facilitate assembly of the parts and permit ready access thereto. llniversally mountedon each of the angularly-entending arms 28 by means of the ball and. socket joints 32, there are massaging elen'ients, comprising the head 33, having a concave surface forv providing an air chamber 34 which is covered by a rubber pad 35 having a plurality of projections 86. On each end of the ma chine and integrally formed with the housing 31 there is a handle 87 for permitting the support well as the manipulation of the device by the operator, or merely the manipulation thereof in conjunction with its support through the medium of the bale 38 secured to the top of the motor housing 10.

From the foregoing, it will be apparent that the reciprooatory action imparted to the supporting frame 24 will cause a similar movement of the massaging elements toward and away from each other, as indicated in full. and dotted lines in Fig. l, the angular position of the elements with respect to each other substantially conforming to the com stantially 'spective massagingelement for tour of the Scalp, while the ball and socket mounting thereof permits adjustment to variations in the curvature.

The invention claimed is:

1. In a massage machine having a housing, a vertically-positioned motor supported substantially centrally thereof, oppositely-disposed massaging elements reciprocably mounted thereon and extending at an angle to each other, a downwardly-extending shaft having a worm thereon driven by said motor, a pair of oppositely-disposed Worm gears meshing on opposite sides of said worm and extending in a vertical plane, and means actuated by said worm gears for imparting a reciprocatory movement to said elements.

2. In a massage machine having a housing, a vertically-positioned motor supported subcentrally thereof, oppositelydisposed massaging elements reciprocably mounted thereon and extending at an angle to each other, a downwardly-extending.shaft having a worm thereon driven by said motor, a pair of oppositely-disposed worm gears meshing on opposite sides of said Worm and extending in a vertical plane, and a cranklike mechanism actuated by each of said gears for imparting a reciprocatory movement to their respective elements.

'3. In a massage machine havlng a housing,

a vertically-positioned motor supported substantially centrally thereof, oppositelydisposed massaging elements reciprocably a motor supported thereon, oppositely-dis posed massaging elements, a pan of worm gears oppositely disposed on each side of said motor and driven thereby, said gears extending in a vertical plane, supporting frames for said massagingelements slidably mounted on said housing, crank mechanism connected with each of said gears for imparting a reciprocatory movement to said frames, and

angularly and downwardly disposed arms formed on each of said frames for supporting their respective massaging elements.

5. In a massage machine having a housing, a motor supported thereon, oppositelydisposed massaging elements, a )air of worm gears oppositely disposed on each side of said motor and driven thereby, said gears extending in a vertical plane and partially onclosed by said housing, end housings mounted thereover and removably secured to said housing for completely enclosing said gears, supporting frames slidably mounted on said housing so as to reciprocate thereon in substantially a horizontal plane, crank mechanism actuated by each of said gears for imparting a reciprocatory movement to said supporting frames, said supporting frames being telescopically associated with said housing for enclosing said mechanism, a pair of angula-rly and downwardly extending arms formed on each of said frames, and a massaging element having a universal connection with each of said arms.

6. In a massage machine having a housing, a vertically-positioned motor supported substantially centrally thereof, a downwardlyextending shaft driven by said motor having a Worm thereon, a pair of oppositely-disposed worm gears positioned to mesh with said worm and extending in a vertical plane, a portion of said worm gears and said worm being enclosed by said housing, end housings removably secured to said housing for enclosing the balance of said gears. supporting frames slidably mounted on said housing, a cam member secured to each of said gears so as to be rotated thereby, a collar surrounding each of said cam members and connected with their respective supporting frames for imparting a reciprocatory movement thereto, said supporting frames being adapted to enclose said cam members and having one side thereof telescopically associated with said housing, downwardly and angularly extending arms formed thereon, laterally extending arms having a bowed portion to pass under said housing and extend downwardly at an angle therefrom on the other side thereof integral with said first-mentioned arms, and a massaging element having a universal mounting on each of said arms.

In witness whereof, I have hereunto afiixed my signature.
